Sara and Jenny can both do flips in the air. The ratio of the number of flips Sara can do to the number of flips Jenny can do is

Snowcat [4.5K]

Wow! I never had problems this hard in middle school!

But you can do it!

First, we need to figure the number of flips Sara can do based on Jenny's.

Jenny = 120 and Sara - 120 x 3/8 (because she is only 3/8 of Sara's)

Calculate 120 x 3/8 = 45 flips

Now we know that Sara increased her amount of flips by 3 (45 +3 = 48)

And we know that Jenny decreased hers by 12 (120 - 12 = 108)

So now we have a ratio of 48:108, but we need to simplify that with factoring.

I am going to divide first by 2.

24:54

Then 2 again...

12:27

How about 3?

4:9

I think that is as far as we can go.

Sara is now doing 4 out of every 9 that Jenny does.

Check it!

108 (Jenny) x 4/9 = 48 (Sara) Yes! It checks.

Question 8 of 13

Linear regression are used to represent scatter plots

The linear regression equation is: $y = -0.223x + 24.081$

<h3>How to determine the linear equation</h3>

Start by entering the table values in a graphing calculator.

From the graphing calculator, we have the following calculation summary

Sum of X = 15
Sum of Y = 117.06
Mean X = 3
Mean Y = 23.412
Sum of squares (SSX) = 10
Sum of products (SP) = -2.23

Hence, the linear regression equation is:

$y = -0.223x + 24.081$
